 SYMPHONY trunk reports "no solution found" when a node limit is enforced.
 See the attached MPS and parameters file. This is with CPLEX or Clp as the
 LP solver. The compile script for both cases is as follows.

 with Clp as the LP solver built with
 ../configure --enable-debug --enable-sensitivity-analysis --disable-openmp

 or with CPLEX with the lp solver with ../configure --enable-debug
 --enable-sensitivity-analysis --disable-openmp --with-cplex-
 lib=-L/usr/local/CPLEX_Studio_125/cplex/lib/x86-64_sles10_4.1/static_pic/
